Johnsonite’s patented Subfloor Leveler System helps eliminate abrupt changes in elevation that tend to trip people up in commercial flooring. They provide a gradual ramp for a smooth transition between two different flooring elevations. Unlike traditional patching compounds, the Leveler System eliminates the need for costly man-hours, long curing time and uncertain results. Instead, the Subfloor Leveler System installs easily and is ideal in high-traffic areas where small elevation changes can cause expensive slip/fall accidents in rubber or vinyl flooring.
